Sink, draining board, table top and the like, manufactured of metal



Oct. 13, 1936. o. T. WEBBER SINK, DRAINING BOARD, TABLE TOP AND THE LIKE MANUFACTURED OF METAL Filed Aug. '11, 1934 Patented Oct. 13, 1936 UNITED STATES PATENT OFFIQE Owen Thomas Webber, London, England Application August 11, 1934, Serial No. 739,476 In Great Britain July 6, 1934 12 Claims.

The present invention relates to improvements in sinks, draining boards, table tops and devices of a like kind, manufactured of metal.

Devices of the above kinds have the disadvantage that considerable noise is caused when cooking utensils, crockery and the like come into contact therewith, due to the fact that a metallic note is emitted thereby. This disadvantage has been overcome, for example, in connection with draining boards, by covering the under side of the draining board with felt or fibre padding and securing the padding in position by means of a supplementary metal plate.

The object of the present invention is to provide means whereby the sound is considerably reduced in a particularly convenient and advantageous-manner without unduly adding to the weight of the device and at a reasonable cost. Moreover the means employed for deadening the sound makes it possible to eliminate places in which insects and vermin are likely to harbour.

According to the invention a method of deadening the sound emitted by kitchen sinks, draining boards, table tops and like devices formed of metal consists in filling spaces on the under side of the device, with a substance comprising a mixture of a filling material of light weight and a binding material.

Again according to the invention there is provided a kitchen sink, draining board, table top or like device wherein spaces on the under side thereof are filled with a substance comprising a mixture of a filling material of light weight and a binding material, for the purpose of deadening the sound emitted thereby when kitchen utensils, crockery or the like come into contact therewith.

The invention will be hereinafter more particularly described with reference to the accompanying drawing, in which:

Figure 1 illustrates a draining board, sink and fillet arranged in position for assembly; and

Figure 2 is a section on the lines 22 of Figure 1, illustrating the under side of the draining board filled in with a sound deadening substance.

Referring particularly to the construction illustrated in Figure l the fillet which completely surrounds the sink unit is formed in four different portions. These portions are the section A, the portions D disposed on the front and back edges of the sink B and the portion E surrounding three sides of the draining board C.

As illustrated most clearly in section B of Figure 1 the fillet is of substantially rectangular section being arranged to form a partially enclosed channel around the edge of the unit. The

fillet is formed with a vertical wall 4 extending upwardly from the upper edge of the sink 2 or the surface of the draining board C and with a horizontal wall 5 extending from the upper edge of the vertical wall 4. Depending from the free edge of the horizontal wall 5 is a second vertical wall 6 arranged parallel to the wall 5 and extending upwardly from the lower edge of the wall 6 is a further horizontal wall 1 arranged parallel to the wall 5 but out of engagement with the wall 4 whereby the fillet only partially encloses a space of substantially rectangular section. In the section A which forms a portion of the fillet, the wall 4 is curved at the. ends thereof to conform with the rounded corners of the sink 2. Furthermore, the ends of the section A are partially cut away so that the upper surface of the fillet at the positions where the curved ends of the wall 4 terminate projects out from the remainder of the surface. As mentioned above, the corners of the sink 2 are rounded while the vertical wall 4 of the fillet portion D is straight so that the ends 8 of the wall 4 do not form a continuation of the vertical wall of the sink2 but are disposed substantially tangential to the rounded corners thereof. When the section A is brought into engagement with the corresponding edge of the sink 2 the vertical wall 4 of the fillet A fits accurately over the edge of the sink 2, the rounded ends thereof conforming with the rounded corners of the sink. In addition the ends 8 of the fillet portions D of the sink 2 fit into rectangular recesses cut in the ends of the section A so that the section A of the fillet joins up with the sink 2 in such a manner that the section A is continuous with the portions D of the fillet. Furthermore, the projecting portions of the section A interlock with the edge of the sink so that when the two sections of the unit are seam welded together a very satisfactory joint is obtained.

The edge of the draining board 0 which engages with the edge of the sink 2 remote from the fillet A is shaped to conform to the edge of the sink. The edge of the board projects beyond the ends of the fillet portion E and consequently when the edges of the sink and draining board are brought together they interlock in the same manner as the sections A and D thus allowing a satisfactory seanr weld to be effected.

After assembling the fillet, sink 2 and draining board C, the latter is filled in on the underside thereof, as illustrated in Figure 2, with a sub stance 9 which serves to deaden the noise caused when cooking utensils, crockery and the like come into contact therewith. The substance 9 is arranged on the under side of the draining board C so that the surface thereof is fiush with the surface of the lower inturned edge of the fillet E. As illustrated in Figure 1, the portion of the fillet comprising the fillet portion D is also filled in with the substance 9 so that the surface thereof is level with the surface of the lower inturned edge of the said fillet. The section A which is seam welded to a side edge of the sink 2 is also filled in with the substance 9 so that the latter forms a continuous surface around the fillet forming the edges of the sink 2 and the draining board C and over the entire under-surface of the latter.

Examples of materials which may be employed as filling materials in the substance 9, are sawdust, hair, fibre, rock Wool, granulated cork, reeds, shavings, shredded wood and the like while examples of materials which may be used as binding materials in the substance 9 are magnesite, plaster, gypsum, asphalt, pitch, light cement or the like. It will be appreciated that these filling and binding materials may be combined to suit individual requirements and that any other convenient materials may be employed provided that the filling material is of light weight and forms a sufficiently hard substance when mixed with the binding material and allowed to set.

The substance 9 may be trowelled over the surface or sprayed in the form of a skin coat to form a smooth surface fiush with the outer surface of the lower edge of the fillet as illustrated in Figures 1 and 2 and the surface of the substance may be coated, after hardening with enamel or paint if desired. As illustrated in Figure 2 a light wire mesh I0 is preferably embedded in the substance 9 to provide reinforcement thereof. Furthermore, dovetailed hardwood ground strips may be placed in position at the time when the substance 9 is applied so that the whole surface is flush and unbroken while the strips form means for readily securing the sink and draining board to wall bracket legs or the like.

It will be appreciated that a table top formed of metal may be coated on the under side thereof with the substance 9 in a manner similar to the manner in which the draining board 3 is coated. If the table top is provided with a fiange or skirting around the edge thereof the substance 9 will be filled in so that the surface thereof is flush with the free edge of the flange or skirting.

The arrangement according to the present in vention thus provides a particularly convenient and cheap method of deadening the noise emitted by a sink, draining board, table top or like device in that the substance employed to fill up the spaces does not appreciably increase the weight of the device and furthermore presents an undersurface which is washable and devoid of crevices, and eliminates any parts in which insects and vermin might harbour. Furthermore, by employing the sound deadening substance filled in on the under sides of the fillets, draining board or table top it is possible to use a lighter gauge metal for the said sink, draining board or table top than would otherwise be practicable if the filling substance was not employed.

What I claim and desire to secure by Letters Patent of the United States is:
